I've got that same sort of xfmr, but I'm only pulling off 24VAC for the light and 120VAC for the coolant pump. I thought about using 120VAC direct from the wall for the pump, but decided i liked the idea of having an isolation xfmr for a pump that's sitting in water.

The original control circuitry used the 24VAC, but the VFD requires 24VDC on its inputs. At the moment I'm planning on pulling that from the VFD itself, but I might wind up dropping a little power supply in there if the current consumption is too high for the VFD to source. A relay coil, a LED, and max of four VFD inputs should be OK, though.

Some more wiring. Using heat shrink in a Brother label maker to tag each end of the wires, and then putting a ferrule on:

Then it's just following the numbers:

Ok, WAY too professional looking. Makes mine look like a rat's nest.

Looking good. Smart move to fasten everything to a back plate rather then trying to wire it up inside the bottom of an enclosure. Looks way more professional as well.

I generally prefer to use L6-30 twist lock plugs for everything. Not nearly as huge.

I use this same type plug on all of my 220V equipment except the 50 amp Tig welder. Make it easier as I can plug in anywhere in the shop.

Making more progress on the wiring:

Ran out of heat shrink and had to use label tape wraps for a few wires. About ready to mount the panel in the box and start connecting to the existing wiring.

Been slacking on posting pictures. The wiring is coming along, slowly but surely:

Initial setup on the added top cabinet:

Routing connections between the cabinets. Trying to keep the power away from the signals:

Front panel wiring:

Rearranged connections from the original front panel. I replaced the cable with one that had more conductors. The original had a common to most of the switches, but I needed direct connections with the added panel and split between 24VAC and 24VDC control circuits.

Still need to move a couple of the existing connections from that barrier block to the DIN block on the right.

Tap talk pics are the dreaded red x's ,

Grrrr...I can see them ok in the edit window, but they disappear on the edit page. Frustrating.
